Erosion control mat



FIG. 1 illustrates a top plan view of an erosion control mat showing our new design;

FIG. 2 illustrates a bottom plan view thereof;

FIG. 3 illustrates a front elevational view thereof, the back and the right and left side elevational views being a mirror image thereof; and,

FIG. 4 illustrates a top front-right perspective view thereof with a plurality thereof shown in broken line in the erosion control mat for lying on a ground surface.

The erosion control mat illustrated in FIG. 1 forms from a fabric envelope of four spaced-apart blocks for enclosing curable hardenable material. The erosion control mat may be used for covering and stabilization of ground surfaces subject to water erosion, separation and vertical drainage layer for marine applications including water channels, and a ballast layer for sinking another material that would normally float and as a protective layer/vertical drainage over such material.

The broken line areas depict portions of the erosion control mat showing environmental subject matter and forms no part of the claimed design. 

CLAIM We claim the ornamental design for an erosion control mat, as shown and described.
